Are you good at matching patterns? How fast can you match them? Pick 3 Tablets with similar or different properties, and create a "Pattrn". The more complex the Pattrn the more you score. The more you score the harder it gets. Three tablets, all green triangles, that is a Pattrn. Three tablets, one green triangle, one red, one yellow, another Pattrn! A green circle, red circle, and another red circle, that is a Fail. Give it a shot, how smart are you?
